Publisher's Synopsis
Excerpt from The Journal of Nervous and Mental Disease, 1919, Vol. 49
It is also desired to record the following facts. In testing the possibility of reflex pathways in the thalamus related to visceral activity, the following experiments have been done. The gastric contractions were studied by the balloon method after previously decerebrating a turtle, leaving the thalamus in situ. In such an animal hunger contractions will occur (patterson). It was found that electric stimulation of this part of the brain stem anterior to the Optic lobes may modify the gastric contractions in either a pos itive or negative way, either of stimulation or inhibition. The same strength of current applied to the meninges did not cause these changes. The positive stimulation resembles that obtained by stim ulation of the medulla but the contractions are not so vigorous. Furthermore the same stimulation will also be followed by cardiac inhibition which may be prolonged. The possibility that these effects may be due to spread of current can not be absolutely ex cluded but the same stimulus applied to the cortex of the Optic lobes did not give these effects.
